1. If you use osg::ref_ptr<> for your Texture2D objects, they should be cleaned up when you remove any references to them (ie just remove the geode(s) the texture is attached to or any other references to the texture)
2. bad_alloc usually means you're running out of memory. On Fri, Jul 26, 2013 at 2:48 AM, Nat Doublet <[email protected]> wrote: > Hi, > I cut an image in 16*16 bitmap files (12M each).
